Doug Mastriano, the Republican candidate for Pennsylvania governor, filed a lawsuit against the Jan. 6 committee on Thursday, seeking to block the panel from compelling him to sit for a deposition.

The lawsuit was filed in federal court in Washington. Attorneys for Mastriano, who is currently a senator in the Keystone State, argued that the Jan. 6 panel does not have the authority to conduct compelled depositions because it is unable to comply with the House Regulations for the Use of Deposition Authority (Deposition Regulations).
